CBSE Science Fair Exhibition Project, “Effective Use Of Solar Energy/Automated Street Light” Theme “Natural Resource & their Conservation” for Class 9, Class 10 and 12

Project Name : Effective Use Of Solar Energy/Automated Street Light

Theme Name : Natural Resource & their Conservation

Objective: To operate the street lights automatically.

Principle: Motion sensing and light sensing.

Working: The light sensor checks the light intensity in the atmosphere, and depending on the amount present in the surrounding, it sends an input to the micro-controller whether light is needed or not. This is then followed by the next stage of the process, when it receives an input from the motion sensor as well, telling the micro-controller if there is motion on the road.

Thus, the street lights only switch on when both the conditions are satisfied. When either one is not satisfied, the lights are not switched on.

Further Scope:

New technology lights similar to LED’s can be developed.

Energy can be conserved by using innovative speedometers in vehicles and this would lead to cost effective street lighting system.

Name of the School: Meridian School, Madhapur, Hyderabad.
